SSPC Protective Coatings Inspector (PCI) Level 1 Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary purpose of surface preparation before coating
- Improve coating color
- Reduce curing time
- Remove contaminants and create a suitable profile
- Increase coating gloss
application?
Rationale: Proper surface preparation is required to remove contaminants
and establish an anchor profile for coating adhesion.
- Which standard is commonly used to assess visible cleanliness of steel
surfaces? 1 / 4
A. SSPC-PA 1
B. SSPC-SP 1
C. SSPC-PA 2
D. SSPC-SP 5
Rationale: SSPC-SP 1 addresses solvent cleaning for removing visible oil,
grease, and contaminants.
- What is the main objective of using abrasive blasting?
- Increase coating thickness
- Achieve cleanliness and surface profile
- Reduce environmental humidity
- Speed up curing
Rationale: Abrasive blasting removes contaminants and creates the
required surface profile for coating adhesion.
- Which instrument is used to verify ambient conditions prior to coating?
- Dry film thickness gauge
- Psychrometer
- Centrifugal blast wheel
- Wet film comb
Rationale: A psychrometer measures dry-bulb and wet-bulb temperatures
to determine dew point.
- What does DFT refer to in coating inspection? 2 / 4
- Diluted Film Thickness
- Dry Film Thickness
- Double Film Thickness
- Dense Film Treatment
Rationale: DFT is the cured coating thickness after solvent evaporation.
- Which SSPC standard describes Near-White blast cleaning?
A. SSPC-SP 2
B. SSPC-SP 3
C. SSPC-SP 10
D. SSPC-SP 11
Rationale: SSPC-SP 10 specifies Near-White blast cleaning requirements.
- What is the purpose of a holiday detector?
- Measure DFT
- Locate discontinuities in coatings
- Determine curing rate
- Evaluate gloss
Rationale: Holiday detectors identify pinholes or voids in non-conductive
coatings.
- Which factor most affects dew point?
- Barometric pressure
- Relative humidity
- Wind speed 3 / 4
- Coating viscosity
Rationale: Dew point is strongly influenced by relative humidity levels.
- Which method is used to measure surface profile height?
- Gloss meter
- DFT gauge
- Replica tape
- Psychrometer
Rationale: Replica tape produces a measurable impression of the surface
profile.
- What is the primary concern when coating over a surface below dew
- Increased viscosity
- Condensation leading to adhesion failure
- Excessive gloss
- Rapid curing
point?
Rationale: Moisture condensation prevents proper coating adhesion.
- What is SSPC-SP 2?
- Power tool cleaning
- Hand tool cleaning
- Waterjetting
